Hi,
It looks like someone is trying to break into my system. This is out of my apache error log...

This is the pattern of the CodeRed virus that was going around the net a few months ago. You are safe from it of course since it is targeted at windows machines running unpatched versions of IIS.

Is there any way I can block this nasty person?
Who should I report this to?
As to who you should report this to I did a lookup on the ip address and this is the data
Search the APNIC Whois database
Search results for '61.243.140.78'
inetnum 61.240.0.0 - 61.243.255.255 netname UNICOM descr China United Telecommunications Corporation descr Beijing Railway Station East Avenue country CN admin-c RX9-AP, inverse tech-c RX9-AP, inverse mnt-by MAINT-CNNIC-AP, inverse mnt-lower MAINT-CN-CNNIC-UNICOM, inverse changed [email protected] 20010817 changed [email protected] 20010828 source APNIC
Since it seems to come from a user in China I doubt there is anything at all you could do.
Even tring to get ahold of the system admins in China is very very hard. I wouldn't worry about it at all it looks like a random scan of your domain and from a client that is set up to scan whole ranges of addresses no worries.
